Patented Nov. 17, 1942 il iE S'ii l2 Claims.

This invention relates to sound making devices and more particularly tosuch as utilize an induced air current in producing sonic vibrations inreed structures.

The main object of this invention is to utilize the inflation period ofa single bellows for the enunciation of two distinct syllables, aspa-pa, and the deflation period for the enunciation of two distinctsyllables as ma-ma, or vice versa, upon being reversed from one uprightposition to an opposite position.

Another object is to provide effective, completely inclosed, reeddevices, productive of articulate sounds upon being reversed withrespect to their ends.

A further feature is in the provision of means whereby the sounds areenunciated in distinct syllables, relatively long and short, at briefintermittencies, accented and modulated harmoniously.

A further purpose is to produce means by which the foregoing aims arefully attained by the relation of few and simple parts, well adapted forlong continued service without failure.

These and other useful objects, further on apparent, are accomplished bythe novel and practical design, construction and combination of parts,hereinafter described and illustrated in the accompanying drawings,constituting a concrete component of this disclosure, and in which:

Figure 16 is another like view showing 1the bellows almost completelyiniiated, as emitting a second syllable.

Figure 1'7 is a sectional view, similar to Figure 14, the position ofthe casing being the same and the parts as reversed from that shown inFigures l5 and 16.

Figure 18 is another like sectional View showing the bellows nearlydeilated.

Referring in detail to Figures 1 to 6 of the drawings, the numeral I5generally designates a cylindrical casing, preferably made of strongpaste-board, and of such dimensions as are compatible with its purpose.

Over one end is a disc I6, that may be of thin metal, having anannularly flanged rim I1, secured circumjacent the edge of the casing inthe manner of a cap, and provided with a plurality of openings I8,except at its central portion I 9, which remains blank.

On the opposite end is a similar cap composed of a disc 23 having aflanged rim 2| and containing a single central vent perforation 22,provided with a exible iiat, flap valve 23 at its inner side, the valvebeing free, except at one point at its edge, where it is attached to thedisc 20.

Disposed within the casing is a highly flexible bellows 25, its outeredge 26 being shown as turned re-entrantly over the edge of the casingI5, cemented thereto and further secured in fixed position by the rim 2lof the cap 2l).

The opposite, inner marginal edge 21 of the bellows material is securedby an adhesive to the exterior portion of a molded weight 30, of heavymaterial, such for instance as porcelain, flanged, as at 3|, in themanner of a cup.

This weight is of lesser diameter than the interior of the casing l5 toprevent the bellows fabric,

when deating, from damage by the wall of the casing and contains acentral opening 32, having a counter-bore 33 in its flanged side.

Fixed rigidly in the counter-bore is a tube 34, to extend outwardlybeyond the weight, to nearly contact the cap I6, causing the weight 30to draw the bellows fabric straight, in order to inflate the bellows toits full capacity.

Telescopically engaged within the tube 34, and slidable through theweight opening 32, is a tubular guide 35 having one end 36 closed andsecured to the cap element IS by any preferred means, as the rivets 31.

Set rmly within the guide 35, at a point near its open opposite end, ina manner to completely close the passage therethrough, is a circularblock 38 having, in the side adjacent the closed end of the guide 35, agroove 39 in which is set one end of a longitudinal partition 4i),extending to make contact with the end wall 36 of the guide, therebyforming two equal air chambers, respectively 4I and 43.

Extending through the block 38 are two sound reeds 42 and 44, arrangedin parallel and in relatively reversed relation, the reed 42communicating with the chamber 4|, and the reversed reed 44 entering thechamber 43.

Formed in the opposite side walls of the tube 34 are passages 45 and 41,which are obviously moved whenever the weight 30 moves.

The guide 35 has ports 46 and 43, shown in Figures l and 3, registerablewith the passages 45 and 41 respectively, upon movement of the weight30.

Reversing the device from the position shown in Figures 1 and 2, to thatof Figures 3 and 4, causes it to draw air into the space within thecasing, via the openings I8, due to the descent of the weight 30,causing the bellows 25 to initially deiiate.

The air current, indicated by the arrows in Figures 3 and 4, is forcedthrough the reed 44, into the chamber 43, which acts as a sound amplier.

The air current is created by the gravitational force of the weight 30,acting on the bellows 25, and causes the reed 44 to vibrate, emitting asound, as ma, through the openings 41 and 48 until the openings becomeclosed, by the sliding movement of the tube 34 relative to the guide 35,the tube 34 being fixed in the weight 30 which acts to operate thebellows.

When the passage 41 and port 48 are closed, a pause in audition iscreated, as the air in the bellows cannot escape through the valved vent22, therefore being forced through the reed 42, which, being in areversed position, acts as a non-vibrant mute valve for the escape ofair only.

As the bellows slowly deflates, and consequently descends, the tube 34,fixed to the weight 3B, is moved to present its outer rim to the port4B, opening it to allow the air, under pressure in the chamberV 43, toescape in a slightly compressed condition, causing the reed 44 tovibrate, emitting a second syllable, as ma Upon reversing the positionof the casing, as shown in Figures and 6, a similar eect is attained inthe production of two distinct syllables, as pa-pa; in this case theiniiation of the bellows is utilized, while its deflation produced thepreviously described eect.

As the weight 30, to which the bellows is secured, descends inflation ofthe bellows begins.

Air is drawn through the port 46 into the chamber 4I, passing throughthe reed 42 into the bellows, causing the reed to vibrate and emit asound, as pan The weight continues downwardly, causing the bellows tofurther inflate, the port 46 is closed by the edge of the tube 34,causing a pause in audition; as the air current is prevented fromentering the bellows 25 through the reed 44, the valve 23 raises,permitting air to enter the bellows.

Continuing, the weight 3B attached to the bellows descends, the tube 34passing the port 4G and causes its passage to register, temporarily,with the port 45 in the guide 35, during which the air flows into thebellows through the reed 42. The slight vacuum created in the chamber 4|accelerates the vibration of the reed by reason of a more rapid flow ofair, causing it to emit a second syllable, as pa.

Drawing air through the reed 42, causes it to vibrate and originate ashort, distinct syllable, thence a quiet period, followed by a longcontinued syllable as the ports and passages arrive at the positionsshown in Figure 1. i

Obviously the device may be constructed to originate more than twosyllable sounds, depending on the position and number of ports andpassages in the elements 34 and 35, and the sounds may be of widelydifferent character, depending on the construction and tuning of thereeds.

In the embodiment, shown in Figures 7 to l2 inclusive, the casing 5U isidentical with that previously described, consisting of a cylinderhaving a plurally perforate cap 5| at one end, and a plain cap 52 at itsopposite end, in which is a single central perforation 53 provided witha flap valve 54.

The bellows 55 is secured at its outer end 56 to the cap 52, while itsinner end 51 embraces and is cemented to a weight 6! freely slidable inthe casing.

The weight has in its level under surface a depression 6|, while on itsopposite surface is a raised hub 62 in which is a central transversegroove 63.

An inverted tubular cup 65 is firmly secured on the hub 62, the cuphaving an imperforate bottom 66 against which is fixed one of the endedges of a plate partition 61, its opposite edge fitting the groove 63,dividing the cup into two equal chambers 68 and 1U, in which arediametrically opposed ports 69 and 1|.

Circumjacent the cup 65 is a sleeve 15, having a flanged base 16 rigidlyfixed to the cap 5I, the cup being telescopically slidable in thesleeve; this sleeve is provided with ports 11 and 19, which areregisterable with the ports 69 and 1| during different stages of weightmovement.

A raised annular rim on the weight is plurally recessed, as at 8|, toreceive a corresponding number of arms 82 of a spider ring 83, the outerends of the arms being flanged and fastened to the wall of the casing50, thereby re-enforcing the sleeve 15 and maintaining it in fixedcentral position.

Set in the central portion of the weight, to extend into the depression6|, is a sound reed 85, while another reed 86 is disposed in reversedposition; thus the reed 85 communicates between the chamber 68 andinterior of the bellows, while the reed 85 connects the air chamber 10with the bellows.

As the method of operation is substantially the same as that of theforegoing device, it will be well understood by persons familiar withthe art.

In the modification shown in Figures 13 to 18, a similar casing |00 isprovided with an imperforzate cap IIII at one 'end and at the other endwitha `cap :|02 having a plurality of perforations |03.

Attached to casing by theY cap IIII, is a bellows |05 secured at itsopposite, inner end to the outer annularly ilanged wall |06 of a webbedweight |01, from the center of which, opposite the bellows, extends acylinder |08 greatly reduced from the diameter of the wall |06 andhaving a chamber |09 open to the bellows.

Below the level bottom wall H0 of the chamber is a plunger head III,uniform in diameter with the cylinder and `having intermediate itslength, .two opposed,v inreaching recesses H2 and H4, both being open attheir outer sides.

The recess H2 Vis partially inclosed by a short down-reaching visor H6,while onthe opposite side a similar but relatively longer projection III partially coversthe recess H4. The head III is thicker on the side H8below the recess H2, than the opposite side H9, thus raising the bottomof the recess I I2, oisettedly from that of the recess H4.

Set in the wall I I0, and pointed in opposite directions, are a pair of.sound producing reeds and |2I respectively, the reed |20 extending fromthe chamber |09 to the recess H2, and the reed I2I from the chamber |09to the recess II4.

Fixed axially in the cap |02 is a tubular member |24 Vto extend adistance within the casing and also outwardly therebeyond, to act as aguide for the head IH which is slidable therein.

When the device is in the position shown in Figure I5, the bellows ismoved down by gravity, air entering the bellows through the perforations|03, recess H4, reed I2I and chamber |09.

Such movement causes the reed IZI to vibrate, producing sound, while theopposite reed |20 is mute; the sound continues until the recess coverIII enters the tubular guide |24, whereupon a quiet period occurs untilthe head I I I passes outwardly beyond the end of the guide, therebyallowing air to enter the recess H4, direct, as indicated by the arrowsin Figure 16, momentarily producing a second sound or syllable ofdiierent tonal quality.

It will be obvious that upon reversing the casing, as in Figures 17 and18, similar but delayed effects are obtained by the reed |20, the delairbeing caused by the oiset relation of parts I I6 and H8 relative to thecorresponding parts II'I and II9.
